Optical Fiber Circulator

Optical fiber circulator is a multi - port non - reciprocal optical device, the light can only travel in one direction. If the signal is input from port 1, it is output from port 2. If the signal is input from port 2, it will be output from port 3 with very little output loss. When the light is input from port 2, it loses a lot when it is output from port 1, and when the light is input from port 3, it loses a lot when it is output from port 1, 2. Because of its high isolation and low insertion loss, Mingtron Photoelectric can produce three-port, four-port, different power, different wavelength optical fiber circulator, the products are widely used in fiber laser, plug and insert multiplexer, two-way pump system, dispersion compensation device, optical fiber sensing, scientific research and other fields.
